Abstract

Multiple service servers can store identification tags, which identify each user, after associating the identification tags with the identification tags of other users; and can also store identification data, which uniquely identifies users across multiple service servers, after associating the identification data with an encryption key for each identification datum. A management server device stores as identification data the user address data encrypted by means of an encryption key that has been generated for each identification datum. A gateway server device receives the identification tags from a first service server, receives the other identification tags associated with the first identification tags, receives the encryption keys associated with the other identification tags, and obtains the encrypted data from the management server. The gateway server device then decodes the encrypted information, and commands delivery that uses the obtained address data.

Claims

1. A management server device which is capable of communicating with a plurality of service servers, each of the plurality of service servers being capable of associating an identification tag which identifies the user within the service server with an identification tag of another user within the service server and storing the identification tag which identifies the user and the identification tag of another user, and further being capable of associating an encryption key for identification information, said each identification information uniquely identifying a user between the plurality of service servers and storing the encryption key with the identification information;

comprising;

a storage device which stores an identification information of one user in a first column and encrypted information in a second column, said encrypted information being obtained by encrypting an address of the user identified by the identification information stored in the first column with the encryption key stored in one of the plurality of service servers, the encryption key being associated with the identification information of the user stored in the first column.

2. The management server device according to claim 1, wherein the encryption key is not stored.

3. The management server device according to claim 1, wherein the service server is capable of associating and storing an identification tag of another user of the service server with one identification tag.
